Here it is! The sequel to Daughters Of Time! I'm so excited for this! Doctor Who really is my favorite show of all time and this AU really feels like my baby. I love it so much. I hope you enjoy it, but if you don't feel free to leave without leaving negative comments. They will be ignored.

Disclaimer: Doctor Who still doesn't belong to me.

A groan. Stirring.

Jack jolted up from his slumped position on the chair in the corner. He started nodding off an hour ago when it became clear that neither the Professor nor the Doctor could do anything to wake the comatose girls. Glancing around the room for the source of the noise, he found both Josie and Billie still laid out on their cots, crisp white blankets covering their bodies to keep them warm. The Doctor was slumped over in his chair, overcoat and jacket gone, sleeves rolled up to his elbows, arms crossed on Josie's bed, and his head laying close to her body. His gravity defying hair was in even more disarray than usual from the amount of times he'd run his hands through it. The Professor was leaning back in his own chair on the other side of the room beside Billie's bed, head lolling on his shoulders and one arm outstretched to hold onto her hand. He too was missing his leather jacket, however, unlike the Doctor's, it was still in sight, wrapped around Billie's shoulders.

Jack grinned as he recalled the Professor gently lifting the unconscious human to put it there, ignoring the pointed stare the other male was throwing him. That poor daft alien was always so overprotective of Billie, but to actually wrap her up in his own coat as if that would help her recover was going a bit far. Jack had opened his mouth to say something teasing to the older man but snapped his mouth shut when the Professor sent him the most intense scowl he'd ever gotten. Not even when he first met the two Time Lords and tried to con them did he get such a heated glare. If looks could kill…

Another groan brought him back to reality. Hard. His eyes darted to both girls, trying to figure out which one was coming back to them. Billie stirred slightly, her eyes tightening as her nose scrunched up and her head turned toward the Professor, as if instinctively knowing he was there. At the same moment, he caught Josie twitch, her hand accidentally smacking the Doctor in the face causing him to jump and nearly fall out of his chair. Jack laughed as he jumped up to stand between the two women he considered sisters, unsure of which one to go to first.

"They're waking up," he exclaimed excitedly at the Doctor's dumbfounded expression. The Professor shot out of his chair, his hand tightening around Billie's as he leaned over her, eyes scanning her face for any sign of consciousness as the Doctor did the same to Josie, squeezing her hand in hopes of getting a reaction.

"Doctor…" the hoarse whisper floated up from the redhead, making the Doctor's face split into a large grin.

"Hello," he said breathlessly, gently tucking a stray lock of hair behind her ear.

"Hello," she answered with a weak grin.

Billie seemed to be waking up as well, the Professor bent so low over her form, Jack could swear he saw his lips brush hers momentarily as he whispered to her, too low for anyone else to hear.

It was quite a while before either couple took notice of Jack again. Billie was now sitting up, the Professor sitting behind her, holding her against his chest like he was afraid she'd disappear if he let go, while across the room Josie was being scanned by the Doctor who was babbling away a mile a minute so not even his brother would be able to understand him.

Billie rolled her eyes and waved Jack over to give him a hug, "God, it's good to be back."

He chuckled, rubbing her back lightly before he let go, "Good to have you back, Jeanie. No more scaring us like that, okay?"

She smiled weakly, leaning back into the Professor's embrace, "Promise."

The Professor sighed as he momentarily buried his nose in her hair, "Want to tell us what you're doing, Theta."

He was quiet, staring wide-eyed at the screen beside Josie's cot, one hand still grasped in the redhead's. His mouth opened and closed a few times, imitating a fish.

"Doctor," Josie tugged on his hand to gain his attention. "What's wrong?"

"Nothing," he whispered, turning to stare at her in shock. "Absolutely nothing. That's the problem. Both you and Billie show no signs that anything has happened."

Josie's brow wrinkled, "Isn't that a good thing?"

"Yes, of course," he nodded hurriedly, "But there should be something to show that you almost…to show what just happened. But by the look of these tests you two may as well have been just napping."

Jack gaped at the Doctor, sinking down onto the cot beside the Professor and Billie, "So…what does that mean?"

The Doctor scratched the back of his neck nervously, "Well, I…er…may have done a more thorough exam when the abnormality popped up…"

"And?" the Professor hissed, tired of the Doctor's rambling.

"Well…Josie and Billie…aren't…exactly….human."

There was a beat of silence before four confused voices shouted, "What!"

The Doctor spun back to the monitor, babbling about extra chromosomes and familiar DNA. Jack pretty much tuned him out, moving to look over his shoulder to see for himself. He was shocked to not only see samples of blood from Josie and Billie labeled on the screen but also one from himself. A few strands were highlighted in each, showing similarities. "They're Human Plus…like me."

The Doctor nodded, "Very much like you, actually."

"Wait," Josie ordered. "What does that mean?"

"A hundred or so years in your future humans begin to evolve. Their basic structures change with every new world they discover, altering so they can survive in each new place until, around Jack's time, they become what people call Human Plus, though only those who travel often through space and time have this level of change. Your cells have already started slowing down. At this rate I wouldn't be surprised if you stopped aging altogether soon. That's about twice as fast as Jack."

"So," Billie tilted her head to the side in thought. "We became Human Plus when we started traveling with you?"

"Yes and no," the Professor answered, sounding a little shell-shocked. "The only way for you to change on that level would be if you were born with that potential. Potential someone from your time shouldn't have." He subconsciously gripped her a little tighter.

"I really don't understand," Josie frowned.

"There's more," the Doctor said, now more eagerly. "It seemed like they were all just a little too similar so I took an even closer look. If you look here, here, and here, you'll see more than just similarities. They're exactly the same."

Jack's eyes widened in understanding, "But…but that means…" a smile began to form on his face. He'd never thought this would be possible. How was this possible?

The Doctor nodded, smiling slightly at the girls as he explained, "It seems, not only are you Human Plus, but you also have the same father."

"What!" both girls shouted.

"And," he continued, ignoring them as he pushed Jack in front of them, gesturing to him dramatically, "Meet your big brother, Jack Harkness."
